RADAR Pulse Repetition Interval Modulation Recognition

This dataset was developed to prepare a novel PRI radar signal dataset. The experiment was conducted at Imam Khomeini marine university, Nowshahr, between September and December 2020. For this purpose, the required system was designed and placed in an environment with a high density of radar signals for eight months. To achieve the desired capabilities and meet the requirements, designed electronic support systems have general sections: radio antennas and receivers; hardware, control, and power supply units; processing units (processor, software, and processor units); and user consoles.
The list of selected equipment for designing the desired system is given in Table 1. This passive system receives, detects, processes, and analyzes radar signals in the frequency range of 2-18 GHz. According to the tasks and requirements, the system consists of two general parts: the external part (i.e., antennas and radio receivers) and the internal part (i.e., processor set and hardware units), and the connection between these two parts via cable interfaces are established. The antenna arrangement pattern according to each antenna’s radiation pattern and coverage and selecting the required number of antennas is designed as an array to cover the entire 360 degrees. Depending on the type of receivers, the system processor can process the output signals of the receivers in real-time.

本数据集旨在构建一套新型PRI（Pulse Repetition Interval，脉冲重复间隔）雷达信号数据集。本实验于2020年9月至12月间在诺沙赫尔的伊玛目霍梅尼海事大学（Imam Khomeini Marine University）开展。为此，研究团队设计了所需的实验系统，并将其部署在雷达信号高密度环境中持续运行8个月。为达成预期性能并满足项目需求，所设计的电子支援系统共包含以下通用模块：无线电天线与接收机、硬件单元、控制单元与电源单元、处理单元（含处理器、软件及各类处理组件）以及用户控制台。
本实验所需系统的选型设备清单详见表1。该无源系统可在2-18 GHz的频率范围内接收、检测、处理并分析雷达信号。根据任务与需求，本系统共分为两大通用模块：外部模块（即天线与无线电接收机）与内部模块（即处理器组件与硬件单元），两模块间通过线缆接口实现连接。天线布阵方案根据各天线的辐射方向图与覆盖范围进行设计，并选用合适数量的天线组成阵列，以实现全360度覆盖。根据接收机类型的不同，系统处理器可对接收机输出的信号进行实时处理。
